Abstract
A method for reporting Channel Status Information (CSI) to a Base Station (BS) by a User Equipment (UE) in a wireless communication system is disclosed. The method includes receiving, from the BS, information on multiple reference signals with a pattern indicator of the multiple reference signals through a radio resource control (RRC) layer, receiving, from the BS, the multiple reference signals, generating the CSI using the multiple reference signals based on the pattern indicator, and reporting the CSI to the BS. Specifically, the pattern indicator indicates whether the multiple reference signals are precoded or not.
